Title: Semiconductor memory system
Inventor: NANBU HIROAKI
IPC: G06F12/08
Filed: 1996-01-17
Abstract: PROBLEM TO BE SOLVED: To accelerate a system by adding a memory for storing addresses when data to be stored in the address of a main memory are different from data to be stored in the address of a cache memory. SOLUTION: A dirty table memory DT is added for storing the addresses when the data to be stored in a certain address of a main memory MM are different from the data to be stored in the address of a cache memory CM. Thus, when the memory DT is added, at the time of write-back processing, it is enough only to write back the data of the address stored in the memory DT and it is not necessary to conventionally check whether update information is written in a dirty bit or not by scanning an index address IA each time write-back processing is performed. Thus, time for write-back can be shortened.

Title: Welding method for forming passive film of chromium oxide on weld zone and welded structure
Inventor: OMI TADAHIRO
IPC: B23K9/235
Filed: 1993-01-18
Abstract: PURPOSE:To form oxidized passive films which have corrosion resistance and extremely less produce out-gases on the surface of a weld zone by coating the ends of materials which are to be welded and have the oxidized passive films essentially consisting of chromium on the surfaces with films contg. the chromium, butting these ends and welding the ends. CONSTITUTION:After SUS 316L pipings are electrolytically polished, these pipings are subjected to an oxidation treatment in an atmosphere of hydrogen and gaseous argon, by which the oxidized passive films contg. a large amt. of the chromium are formed on the inside surfaces. Both ends thereof are then subjected respectively to a chrome plating treatment. The ends of both pipings are thereafter butted against each other and the pipings subjected to the chrome plating treatment are welded by a tungsten inert gas welding method. As a result, the passive films of the chromium oxide having the surfaces which are excellent in acid corrosion resistance, are small in adsorption of moisture content and enable the easy removal of the moisture by low energy in spite of adsorption of the moisture thereon are formed in the weld zone and the parts near the weld zone during the welding stage.

Abstract: PURPOSE:To prevent the clogging of a helium introducing pipe by providing a gate valve to the top end of a sample chamber and providing further a preparatory chamber for sample exchange to the upper part via a valve. CONSTITUTION:The preparatory chamber 14 for sample exchange which permits vacuum evacuation and purging by gaseous helium and is connected to the sample chamber 1 is provided. A gate valve 12 is provided between the chamber 14 and the chamber 1. A sample holder 6 is pulled up and is placed in the chamber 14 above the valve 12. The inside of both the sample chamber 1 and the preparatory chamber 14 is filled with the gaseous helium in this state and the valve 12 is open. The sample is then exchanged by shutting the valve 12 to isolate the chamber from the external air and opening an inlet and outlet 13 for sample exchange. The inside of the chamber 14 is then evacuated to a vacuum and is purged by the gaseous helium so as to be filled with the gaseous helium and thereafter the valve 12 is opened and the holder 6 is lowered to the measuring position. There is no possibility of the intrusion of the air into the chamber 1 at all according to such procedure. The clogging of the liquid helium introducing pipe 8 as a result of the freezing of the air incorporated into the pipe 8 so as to close the flow passage for the helium is entirely obviated.

IPC: B60T8/26
Filed: 1978-01-23
Abstract: PURPOSE: To obtain an appropriate oil pressure rising characteristic and reduce the size of a proportioning valve, by providing two oil pressure lines in the valve of shortened axial length and by maintaining the communication between an input and an output oil chambers of one line when the other line is defective.  
     CONSTITUTION: A first piston 7 is slidably fitted in a first valve cylinder 2. A second piston 9 extends through a second valve cylinder 3. The pistons 7, 9 integrally serve as control pistons. A balance piston 14 is slidably fitted in an inner cylinder 8. The ends of the piston 14 face coil chambers a1, b1 of both the lines. The length of balance piston 14 balances the oil pressure of the output oil chambers. The movement of the balance piston 14 toward the oil chamber a1 is prescribed at a fixed value. When the line (a) becomes defective, the control pistons 7, 9 and the balance piston 14 move right. Since the degree of moving freedom of the balance piston 14 is low, a check valve opens a passage 24 and the communication between the output oil chambers can be maintained. The size of the proportioning valve can be reduced by shortening the axial length of the pistons.

Abstract: PURPOSE: To simplify the open/close mechanism and the controlling software of a shutter by providing a means for switching a light-shielding part from/to a lens set on an exposure shaft by moving a lens base having the light-shielding part and a lens attaching part. CONSTITUTION: A zoom lens 13a or a variable focal lens 13b which satisfies exposure condition is positioned on the exposure shaft L by moving the lens base 11. Thus, an optical path is opened to the zoom lens 13a or the variable focal lens 13b through an aperture part 5(B). Next, the shutter is opened, so that a negative image is recorded on a photographic paper by being irradiated with the exposure light. When exposure operation on the photographic paper is finished, the shutter is closed to shield the exposure light. Then, the lens base 11 is moved and the lens 13 is detached from the exposure shaft L, and also the reflecting mirror 13c is positioned on the exposure shaft L. Thus, scattered light is shielded by closing the aperture part 5 by means of a light- shielding member S3.
